Martin Schiller 798d613afb net/x25: Fix overflow when accumulating packets 
[ Upstream commit a1822cb524 ]

Add a check to ensure that `x25_sock.fraglen` does not overflow.

The `fraglen` also needs to be resetted when purging `fragment_queue` in
`x25_clear_queues()`.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
